Answer:

<h3>               YES</h3>

Step-by-step explanation:

relation is a function if we have y for every x from domain and for one x we have one and only one y

x = 1  --> y = 2

x = 2 --> y = 2

x = -2 --> y = 2

no x-es without y-es

and no two the same x-es with one y

so this relation is a function

Naddik [55]

Answer:

P(x) = 15x^2 + 2x + 4

Step-by-step explanation:

To simplify:

combine like terms

8x^2 + 7x^2 = 15x^2

There are no other like terms.

This equation cannot be simplified any further with the given information.

P(x) = 15x^2 + 2x + 4

The variable z has a standard normal distribution. find the value z such that the event z &gt; z has proportion 0.08. z = –1.41
andrezito [222]

The appropriate choice is z = 1.41.


The empirical rule tells you 68% of the distribution is within 1 standard deviation, so p(z > 1) ≈ 0.17. This means the z value is more than 1 for the probability to drop to 0.08. The only choice that is greater than 1 is 1.41. (The number is actually about 1.40507.)
